Expert Answer:

 
NO2 has an unpaired electron. Hence it behaves as typical odd electron molecule. Because of the presesnce of an unpaired electron, it has a tendency to dimerise to N2O4, with even number of electrons.
ClO2 is also an odd electron molecule, but it is stabilised by resonanace. Hence, it does not undergo dimerisation.
